WebRheologically, the consistency is described by two components, the viscosity (thickness, lack of slipperiness) and the elasticity ('stickiness', structure). In practice, therefore, rheology stands for viscosity measurements, characterisation of flow behaviour and determination of material structure. WebThe most commonly used rheological method to quantify thixotropy is a three-step flow test. This method is used to measure low to mid viscosity samples. In the first step, sample viscosity was measured under low shear rate (e.g. 0.1 1/s). This low shear viscosity represents sample’s status at rest condition. Webrelated to the rheological measurements. The project was supported by The Research Council of Norway (grants no. 118028/112 and 127202/130). LITERATURE CITED fish import philippines
